Electronegativity (Pauling scale)

Notes

* Separate values for each source are only given where one or more sources differ. * Electronegativity is not a uniquely defined property and may depend on the definition. The suggested values are all taken fro
WebElements
as a consistent set. * Many of the highly radioactive elements have values that must be predictions or extrapolations, but are unfortunately not marked as such. This is especially problematic for francium, which by relativistic calculations can be shown to be less electronegative than caesium, but for which the only value (0.7) in the literature predates these calculations.
